All Natural Whey? is an all natural source of protein that was designed to meet the protein needs of all age groups and is number one in digestion, absorption, utilization and retention. This is achieved by using a combination of ultra filtered, low temperature processed whey protein concentrate and cross flow micro-filtrated whey protein isolate. All Natural Whey? is also highly concentrated in essential amino acids (about 50%), half of which are "branched chain" (muscle preserving) amino acids (BCAAs). In fact, it is the richest natural source of BCAAs. All Natural Whey? can benefit those with a wide variety of health concerns ranging from the exceptionally healthy athlete to those trying to support lean muscle mass (e.g. children, teenagers, less active individuals as well as elderly). All Natural Whey? is also fortified with L-Glutamine, which has been shown clinically to naturally stimulate the release of growth hormones and act as a building block for one of the body's most important water-soluble antioxidants, glutathione. Whey protein is nutritionally perfect, meaning it contains all of the essential and non-essential amino acids required by the human body.
